Viewer-Centric Interface for Stereoscopic Cinema Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Directors and filmmakers face challenges in visualizing and planning 3D scenes, leading to substantial planning, re-shooting, and re-planning due to the unpredictability of stereoscopic effects on viewers, such as eye strain and discomfort.
Innovation Solution
A viewer-centric user interface that allows manipulation of parameters like vergence, interocular distance, field of view, and dolly to simulate and adjust the 3D scene from a top-down perspective, enabling planners to preview and edit stereo scenes interactively, applying these parameters to camera settings for desired effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If directors and filmmakers shoot 3D scenes without being able to visualize stereoscopic effects, then they can proceed with production, but they experience substantial planning, re-shooting, and re-planning due to unpredictable viewer experience
Solution Approach 1:
The patent applies preliminary action by providing directors and filmmakers with a visualization tool that simulates stereoscopic effects before actual shooting. The system allows users to adjust camera parameters (interocular distance, vergence, dolly) and preview the 3D effect on a virtual screen, enabling them to make decisions about scene composition and stereoscopic effects in advance, thereby avoiding costly re-shoots
Solution Approach 2:
The patent uses copying by creating a virtual model of the filming scene that replicates the actual camera setup and stereoscopic parameters. The system generates a simulated view from the viewer's perspective, allowing directors to evaluate the 3D effect without capturing real footage, thus enabling iterative planning without physical re-shooting
2Object-affected harmful factors
If stereoscopic effects are enhanced to provide better 3D viewing experience, then viewer immersion improves, but eye strain and discomfort increase
Solution Approach 1:
The patent applies dynamics by providing an interactive interface that allows directors to dynamically adjust stereoscopic parameters (interocular distance, vergence angle, dolly position) and immediately see the effect on the simulated 3D view. This enables real-time optimization of stereoscopic effects to achieve the right balance between immersion and viewer comfort
Solution Approach 2:
The system implements feedback by displaying the simulated stereoscopic effect back to the director through the virtual screen view. This visual feedback loop allows directors to assess the impact of parameter adjustments on viewer experience and make informed decisions to minimize eye strain while maintaining effective 3D effects
3Loss of information
If directors want to accurately predict viewer experience, then they need to simulate from viewer's perspective, but conventional tools only provide director's viewpoint
Solution Approach 1:
The patent applies dimensionality change by switching the viewpoint from the director's overhead/camera perspective to the viewer's screen-level perspective. The system renders the scene as it would appear on the projection screen, allowing directors to see depth relationships and stereoscopic effects from the actual viewing position, thereby recovering lost perspective information
Data Source
AI summary
Described is a user interface that displays a representation of a stereo scene, and includes interactive mechanisms for changing parameter values that determine the perceived appearance of that scene. The scene is modeled as if viewed from above, including a representation of a viewer's eyes, a representation of a viewing screen, and an indication simulating what each of the viewer eyes perceives on the viewing screen. Variable parameters may include a vergence parameter, a dolly parameter, a field-of-view parameter, an interocular parameter and a proscenium arch parameter.
